Thank you for your help I tried Instruction* p=&( Bb->front()); Type * Int32Type = IntegerType::getInt32Ty(getGlobalContext()); AllocaInst* newInst = new AllocaInst(Int32Type,"flag", p); that works well but I need to store the value of the variable too. What's the method that could be used to store specific value?? On 30 July 2013 16:01, John Criswell

Hi, For the following code const Type * Int32Type = IntegerType::getInt32Ty(getGlobalContext()); AllocaInst* newInst = new AllocaInst(Int32Type, 0, "flag", Bb); Bb->getInstList().push_back(newInst); It gives me the error " error: no matching constructor for initialization of 'llvm::AllocaInst' AllocaInst* newInst = new

Hi, I need to insert new instruction into every basic block like x=1 or while loop I tried this code, but it doesn't work Type * Int32Type = IntegerType::getInt32Ty(getGlobalContext()); AllocaInst* newInst = new AllocaInst(Int32Type,"flag", Bb); Bb->getInstList().push_back(newInst); the error: void llvm::SymbolTableListTraits<llvm::Instruction,

I show you the trace of calls to llvm that my compiler makes to generate the code above. bloques.back().last is of type Value* and bloques.back().bl is BasicBlock* (the current Block) bloques.back().last = dyn_cast<Value>(ConstantInt::get(Type::getInt32Ty(getGlobalContext()), $1, true)); // $1 is an int AllocaInst *alloc = new AllocaInst(

Hi, I'm Ryo Ota. I have two questions about `llvm::LLVMContext`. Q1) What is the difference between the following (A)`my_context` and (B)`global_context`? Do I have to create a LLVMContext by myself? Or use `getGlobalContext()`? Could you tell me what situation needs a LLVMContext which is created by myself such as (A)? (A) { llvm::LLVMContext my_context; // codes using only my_context (get

To ease this transition, I have added a getGlobalContext() API. If you're only ever planning to use LLVM on a single thread, it will be completely safe to simply pass this value to every API that takes an LLVMContext. --Owen On Jun 30, 2009, at 3:38 PM, Owen Anderson wrote: > Notice of a major upcoming API change: The static methods for > constructing types and constants will

Notice of a major upcoming API change: The static methods for constructing types and constants will be going away in the future. Instead, the global uniquing tables that lurk behind these APIs will be privatized within LLVMContext instances. What this means for you: Your client application will need to create an LLVMContext in main(), and pass it into a few APIs (the constructor for

Hi all; I have been trying to use the llvm::ConstantArray::get(llvm::LLVMContext&, llvm::StringRef, bool) function but seems it has been deprecated.

I am trying to get a handle on IR builder, at least some basics. I ran through a tutorial here: Create a working compiler with the LLVM framework, Part 1 <http://www.ibm.com/developerworks/library/os-createcompilerllvm1/>, and it worked well enough. I have some simple code that creates a hello world IR. I am trying to now bring in some concepts from the Kaleidoscope tutorial, namely

Hi everyone, I'm having some problems when loading values. Here's a simple example of the IR that my compiler generates to show the problem: define i32 @main() { entry: %a = alloca i32 ; <i32*> [#uses=2] store i32 1, i32* %a %r = load i32* %a ; <i32> [#uses=1] br label %Return Return:

Hi Justin, my class is a visitor pattern and I use accept method to go recursive in suboject in my AST. In locals I store AllocaInst pointer. void *visit(var1_init_decl_c *symbol) { llvm::Type *lType; varNames.clear(); varType = ""; symbol->var1_list->accept(*this); /* get a vector contains variable names */ symbol->spec_init->accept(*this); /* Store in

Thank you very much for you help, Renato! I read through paper you referred and also this document - http://llvm.org/docs/tutorial/JITTutorial1.html Following these instructions to create successful function I run into some problems: 1) llvm::getGlobalContext() does not exists anymore? "llvm/LLVMContext.h" too? 2) creating instance of IRBuilder don't require template (from tutorial

Hi all, I've started work on a new programming language for which I am considering using LLVM as the backend, and trying to experiment with it using the Kaleidoscope demo compiler. Taking the full source listing from http://llvm.org/docs/tutorial/LangImpl3.html#code and trying to compile it with the provided instructions gives me the following errors: a at a-desktop:~$ g++ -g -O3 toy.cpp

Probably you missed to install llvm-dev package with headers for llvm. 2010/1/4 Russell Wallace <russell.wallace at gmail.com> > Hi all, > > I've started work on a new programming language for which I am > considering using LLVM as the backend, and trying to experiment with > it using the Kaleidoscope demo compiler. > > Taking the full source listing from >
